MOUNTlNG-BOARD FOR STEREOTi'PES AND OTHER PLATES Patented Aug. 3.4, 1906.

To all whom it may concern:

Be it known that I, ALFRED JOHN PARKER, a subject of the King of Great Britain, residing at 5 Macleans Buildings, city of London, England, have invented certain new and useful Improvements in Mounting-Boards for Stereotypes and other Plates, of which the followin is a s ecification.

The object 0 this invention is to provide a board on which stereo, electro, since, and other plates used in letter-press printin can be mounted on an absolutely true her and which shall not warp or become distorted through damp or heat.

My invention will be clearly understood from the following description, aided by the accompanying drawings, in which Figure 1 is an end view of two of the wood strips joined together, such stri s being employed in forming the mountingcard. Fig. 2 is an end view of the T-ir0n from which is formed the frame with which the board is surrounded, thus securing the wood strips together. Fig. 3 is a side view of a strip of wood, showing the groove along the grain of the wood and at the slot at the end across the sin for reception of one leg of the Tpiece. ig. 4 is a pers ective elevation of a complete board wit the wood strips running at an angle thereto. Fig. 5 is a similar View with the strips of wood running at two different angles. Fig. 6 is a similar view with the strips of wood running lengthwise of the hoard.

For the purpose of my invention I maize my board from a number of strips of wood A of the same thickness, each strip having its edges B B running with the grain of the wood of siightly concave or touch shape 0 on one side and convex or mortised, as at D, or of equivalent shape on the other edge B, so that when placed together the tenoned edge B of one strip will fit into the inortised edge B of the next strip, the grain of each stri extending in the direction of the lengtli thereof, and the said strips are so arranged with respect to each other that the grain of the strips will extend in an alternate manner with res ect to each other-that is to say, the grain 0 one strip extends in one direction, the grain of the adjoining strip extends in the opposite direction with respect to the grain of the other strip. Such an arrangement of the rain is carried on throughout the board.

The end edges F of the boards A are rooved or recessed at G for receivin the leg I of a piece of T-iron I, the ends of w hich are secured by screws J to the board, thereby giving great stren th and rigidity. The leg of T-iron may be rther secure by pins at intervals, driven through from the surface of thcboard. The exposed surfaces'of the board are chemically treated to resist darn ness.

Thus completed my board is reac y to re ccive stereo and other plates which may be mounted in the ordinary way.

When the board is constructed with the grooved strips A running die onally across, as at Fi s. 4 and 5, the T -iron% extends right round t is board; but when the wood stri s run straight across or down the board the T-iron I need only be placed at the end of the wood strip A with the projecting ends of the T-iron turned up end screwed to the sides of the two outside strips of wood, as will be understood by reference to Fig. 6.

What I-cleim, and desire to secure by Letters Patent, is V 1. A mounting-board for stereotype and other plates having its upper surface in the same plane throughout and comprising a plurality of wooden strips mortised together and having the grain of each strip extending in the'direction of the length thereof, said strips so srrenged with respect to each other that the grain of the strips will extend in en alternate manner with respect to each other, and means for bodily securing the strips together.

2. A mounting-board for stereotype and other plates having its upper surface in the same plane throughout and comprising a plurality of wooden strips mortised together and having the grain'of each strip extending in the direction of the length thereof, said strips so arranged with respect to each other that the grainoi the strips will extend in an altennate manner with respect to each other, and means engaging in the ends of the strips fo bodily securing them together.

3. A mountin -boerd for stereotype and other plates having its up er surface in the same plane throughout an comprising a plu- ISO rality of wooden strips en aging with each other and having their en s provided with grooves and having the grain of each strip extending in the direction of the length thereof, said strips so arranged with respect to each other that the grain of the strips will extend in an alternate manner with respect to each other, and means extending in the grooved end of the strips and secured to the ends of the strips for bodily securing the 10 strips together.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
